上が見られない、などの課題があった。However, (a) when the above metal or alloy is coated by the CVD method, the non-metallic component in the underlying hard coating layer diffuses and lower carbides are easily formed. (B) When the metal or alloy is coated by the PVD method, the coating is performed in a high vacuum, so that the coating layer is oxidized and brittle after coating. (C) When the metal or alloy is coated by the electroless plating method, the adhesion to the underlying hard coating layer is insufficient, so that the fracture resistance is reduced. There was a problem that sufficient improvement was not seen.
